Hi everyone, I am currently using ActiveCollab but it lacks the typical CRM features. I can't even keep notes about a customer saved in one place.

What I am looking for is a simple but efficient CRM application that allows me to store all the (potential) customers along with their phone calls noted down, contracts, agreements.

On the billing end, I should be able to keep track of invoices and payments, along with a bit of sales reports.

A great extra would be a ticket support feature but not really necessary

I looked at VTiger and SugarCRM at first. Though, they look too complex on the sales/campaigns end but completely lack the billing side.

Do you have some good apps/services to suggest? :) Any programming language or OS would do. Both paid and free.

Thanks Mike
